Pin third_party/upb to C17.
Upstream has fixed this (though I can't point to the SHA because they just do code dumps from google3), but we're unlikely to take that update any time soon, and creating a merge conflict by manually patching the two affected lines (because I can't cherrypick because there isn't a SHA with just those fixes) seemed like a worse option.
